Sauce Connect tunnels for the Legacy RDC platform in our EU data center would not start.
A server hosting Sauce Connect components was power cycled and restarted with a faulty DNS configuration. A load balancer didn't recognize that the instance was faulty and continued to serve traffic to it.
We fixed the faulty DNS configuration which caused the instance to recover.
We are updating all DNS configurations for the affected cluster to make sure this problem doesn't occur again. In addition, we will improve the health check for this service to make sure we detect faulty instances properly and stop sending traffic to them.
